Key Staff

The trustees of the Foundation have purposively kept the cost of administration well below averages for foundations nationally. To this end, the office includes only one full-time staff person and one part-time office manager. The Bank of Hawaii's Charitable Trust Division manages the fiscal affairs of the Foundation through an annually reviewed contract.

Al Castle serves as Executive Director and Treasurer. The great-great grandson of founder Mary Tenney Castle, he has been the Foundations' full-time executive director since 1998. Mr. Castle has served as an educator, author, lecturer, community volunteer, fund raiser and non-profit manager for nearly 40 years. His accomplishments in the above fields have been noted in Who's Who in America and Who's Who in the World. The author of two books and over 50 book chapters, journal articles and encyclopedia essays, Mr. Castle is a 5-time recipient of National of Endowment for the Humanities grants and is a past William Coolidge Fellow at Episcopal Divinity School in Cambridge. He is a Phi Beta Kappa graduate of Colorado State University (BA, MA in History) and has also studied at the University of New Mexico, the University of Virginia, and Columbia University. His research and writing has focused on philosophy, diplomatic history, Hawaiian history, the history of American philanthropy, and foundation management.

Mr. Castle has been a frequent presenter at national and regional conferences and served as Chairman of the Council on Foundation's National Family Foundation Conference in 2006. He is currently a board member of the Early Education Funders' Collaborative in Washington, DC.
